Apparatus and process to create, expand, and localize the population of stem cells in adult tissues by placing a foreign body either in omentum or in the subcutaneous tissue. The apparatus 1) traps the granulation fluid, cells a fluid rich in a myriad of growth factors, 2) mobilizes and concentrates free-floating stem cells in the granulation fluid and 3) stimulates the growth of a new tissue around the apparatus, which provides another source of stem cells. Stem cells obtained by this process can be used as freshly isolated or after culturing, which can be used for wound healing, treating diseases, and regenerating organs in animals and humans. The granulation fluid could substitute the stem cells in many of their applications and offers the convenience of an injectable medicine for treating animal and human diseases
